Log:
Remove assumption that drive letters are always uppercase.

* file_io/win32/filepath.c:
  (same_drive): new helper function
  (apr_filepath_merge): use helper rather than a simple comparison

* test/testnames.c:
  (merge_lowercasedrive): do some tests with lowercase drive names

//Machine/share might have similar issues, but not this specific one as Windows doesn't allow setting the current directory to a UNC share.

(The share name can be case sensitive depending on which server architecture you use (E.g. Samba). The machine name is mostly case insensitive)

We needed this on 1.4, I'll add to 1.5 later tonight, and I'll refactor
once again for the //Machine/Share/ syntax later (since we believe it
can also fall out of case-synchronization).
